When I think of our client engagements surrounding voice deployments with Microsoft Lync, I often find myself drawing parallels to issues common to any VoIP deployment. This reflects that regardless of any vendor’s particular implementation of VoIP, they all follow the same core principles and dependencies. Key among these are having a solid understanding of network readiness and End User calling behavior.
This entails assessment and discovery around the following network components:
- Overall Network Topology. Understanding the layout of the networks various sites, datacenters and network edge locations.
- QoS Implementation. The extent of a networks QoS configuration, or its current potential for implementing QoS.
- Stress Testing. Getting a baseline of how the network handles simulated VoIP traffic workloads.
- PSTN Termination. Understanding the layout of PSTN circuit termination within the network environment.
This is of critical importance, and something that is often overlooked in relation to Lync Enterprise Voice implementations. Regardless of the optimized protocols used by Lync for audio and video, it is as susceptible as any VoIP platform to issues of packet loss, jitter and lack of proper QoS prioritization of real time media streams. All of which will have future impacts to audio and video performance if not assessed and planned for properly prior to implementation.
End User Calling Behavior
Understanding end user call behavior and the required feature set is core to deciding on the level of deployment and integration necessary for Lync Enterprise Voice. Having a solid understanding of the following aspects of the voice requirements, helps us to solution the appropriate design for our clients:
- Handset versus soft client requirements
- Handset integration required:
- IP Phones Optimized for Lync (Lync Phone Edition)
- IP Phones Compatible with Lync (Manufactures software)
- Remote Call Control of 3rd party handsets
- PABX Interoperability:
- Client side Integration
- Direct SIP Integration
- Gateway Integration
- Remote Call Control Integration
- Response Group and Contact Center features
- Conference room end point support
End to End Solutions
Microsoft Lync is a very flexible product and has a deep breadth in the levels of integration with which it can be deployed. Long Views deep expertise in network design and VoIP implementation are a great foundation to help clients arrive at a design for Microsoft Lync which integrates into their overall voice architecture. From procurement, to licensing, to professional services, Long View can provide that end to end solution for Lync Enterprise Voice.
